Here is a minor typing error:

 

Lemma 7 If T1 is faithfully interpretable in T2 and T2 is faithfully interpretable in T2,

then T1 is faithfully interpretable in T3.

 

I think you mean the bold red T2 to be T3.

Hi Ali,

here is the submitted version of the modularity paper.

You can put it up on your own url somewhere until it is

accepted by Applied Ontology.
